While the technology industry talks about the superpowers of artificial intelligence (AI), incorporating it in business applications is not easy. Even for the most tech-savvy individual, AI is complex and intimidating technology. There have been many efforts in making AI accessible to developers, but there is still a lot of plumbing that needs to be done. From acquiring the data to labeling it and training the model to optimizing it, deep learning and AI demand niche skills that combine mathematics with data science. After all the effort, utilizing a fully trained model with applications is another tricky task.

Alzheimer's disease (AD) is a neurodegenerative disorder that affects a significant proportion of the older population worldwide. It causes irreparable damage to the brain and severely impairs the quality of life in patients. Unfortunately, AD cannot be cured, but early detection can allow medication to manage symptoms and slow the progression of the disease. Functional magnetic resonance imaging (fMRI) is a noninvasive diagnostic technique for brain disorders. It measures minute changes in blood oxygen levels within the brain over time, giving insight into the local activity of neurons.

Unless you're a physicist or an engineer, there really isn't much reason for you to know about partial differential equations. After years of poring over them in undergrad while studying mechanical engineering, I've never used them since in the real world. But partial differential equations, or PDEs, are also kind of magical. They're a category of math equations that are really good at describing change over space and time, and thus very handy for describing the physical phenomena in our universe. They can be used to model everything from planetary orbits to plate tectonics to the air turbulence that disturbs a flight, which in turn allows us to do practical things like predict seismic activity and design safe planes.

As an engineering director leading research projects into the application of machine learning (ML) and deep learning (DL) to computational software for electronic design automation (EDA), I believe I have a unique perspective on the future of the electronic and electronic design industries. The next leap in design productivity for semiconductor chips and the systems built around them will come from the fusion of fully integrated EDA computational software tool flows, the application of distributed and multi-core computing on a broader scale and ML/DL. The current wave of artificial intelligence (AI) and ML innovation began with improved GPU computing capacity and the smart engineers who figured out how to harness it to accelerate deep neural network training. AI/ML will play a key role in the design of next-generation platforms, enabling the proliferation of today's technology drivers including 5G, hyperscale computing and others. In my role, the fun comes from the numerous non-deterministic polynomial (NP)-hard and NP-complete problems that exist at every stage of the design and verification process.

We are near the end of the hype cycle for artificial intelligence (AI). The human champion of the game of Go decided to retire, saying AI cannot be beaten after AlphaGo defeated him. Domain-specific chatbots are engaging with customers and providing them with the answers they need. AI is about to revolutionize our broken health-care system. Is your company ready for AI? Anyone with deep data claims to be using AI.

First of all, to say that today, predicting as such the exact market structure that will happen in X given time, is not possible, I'm sorry:( . This is due to factors that are unknown in advance, since the future price does not depend only on the past price, but also on macroeconomic changes and concrete business decisions. Examples of this are the advanced recurrent neural networks (RNN) or the new LSTM, they are going to give us a late prediction, although at first sight they seem good, they will have a certain delay. However, we would have to approach the market with another strategy if we want to implement neural networks, but this will be in another article. In this article we are interested in explaining how we can establish a maximum and minimum price for any asset (in this case we will work on American equities) with a certain probability.

The origins of deep learning and neural networks date back to the 1950s, when British mathematician and computer scientist Alan Turing predicted the future existence of a supercomputer with human-like intelligence and scientists began trying to rudimentarily simulate the human brain. Here's an excellent summary of how that process worked, courtesy of the very smart MIT Technology Review: A program maps out a set of virtual neurons and then assigns random numerical values, or "weights," to connections between them. These weights determine how each simulated neuron responds--with a mathematical output between 0 and 1--to a digitized feature such as an edge or a shade of blue in an image, or a particular energy level at one frequency in a phoneme, the individual unit of sound in spoken syllables. Programmers would train a neural network to detect an object or phoneme by blitzing the network with digitized versions of images containing those objects or sound waves containing those phonemes. If the network didn't accurately recognize a particular pattern, an algorithm would adjust the weights.

The success of deep learning, a brain-inspired form of AI, has sparked interest in understanding how the brain could similarly learn across multiple layers of neurons. However, the majority of biologically-plausible learning algorithms have not yet reached the performance of backpropagation (BP), nor are they built on strong theoretical foundations. Here, we analyze target propagation (TP), a popular but not yet fully understood alternative to BP, from the standpoint of mathematical optimization. Our theory shows that TP is closely related to Gauss-Newton optimization and thus substantially differs from BP. Furthermore, our analysis reveals a fundamental limitation of difference target propagation (DTP), a well-known variant of TP, in the realistic scenario of non-invertible neural networks. We provide a first solution to this problem through a novel reconstruction loss that improves feedback weight training, while simultaneously introducing architectural flexibility by allowing for direct feedback connections from the output to each hidden layer. Our theory is corroborated by experimental results that show significant improvements in performance and in the alignment of forward weight updates with loss gradients, compared to DTP.
